AUDIO T I Symptom: Poor sound quality or noise (Radio) 1 ,, Possible cause Damaged cassette tape Damaged speaker Damaged antenna Damaged audio unit Open circuit in wiring harness Poor connection of connector 45UOTX-245 Step 1 1. Tune to the strongest AM station using the automatic memory function. 2. If the automatic memory function does not operate, go to Step 4. 3. Compare sound quality with that of another vehicle that has the same type audio unit. 4. If the sound quality is inferior to the other unit, go to Step n L. 5. If the sound quality is the same as the other unit, the sys- tem is OK. Step 2 1. Play a known good cassette tape, and compare the sound quality with another vehicle that has the same type audio unit. 2. If the sound quality is inferior to the other unit, the mal- function may be in the speaker circuit. Go to Step 3. 3. If the sound quality is same as the other unit, the mal- function may be in the antenna circuit. Go to Step 4. Step 3 1. Check for damage to the speakers. 2. Check for proper connection of speaker connectors. 3. Disconnect the speaker connectors, and measure resis- tance of each speaker. Resistance: 452 4. If a speaker has incorrect resistance or is damaged, re- place it. 5. If the speakers are OK, replace the audio unit. Step 4 1. Check that there is no continuity (infinite ohms) between the mast antenna and a body ground. 2. If there is continuity, replace the antenna. 3. If there is no continuity, go to Step 5.
